Abstract: In some examples, an apparatus includes a first transistor, a second transistor, a third transistor, and a fourth transistor. The first transistor has a source, a gate, and a drain, the drain of the first transistor coupled to a voltage supply terminal. The second transistor has a source, a gate, and a drain, the gate of the second transistor coupled to the gate of the first transistor, and the source of the second transistor coupled to the source of the first transistor. The third transistor has a first terminal and a bulk, the bulk of the third transistor coupled to the drain of the second transistor. The fourth transistor has a first terminal and a bulk, the bulk of the fourth transistor coupled to the drain of the second transistor and the first terminal of the fourth transistor coupled to the first terminal of the third transistor.

Abstract: An integrated circuit (IC) includes: first and second transistors having a respective first terminal, a respective second terminal, and a respective control terminal; and cascode circuitry having a first terminal, a second terminal, a third terminal, a fourth terminal, a fifth terminal, and a sixth terminal. The first terminal of the cascode circuitry is coupled to the control terminal of the first transistor. The second terminal of the cascode circuitry is coupled to the control terminal of the second transistor. The third terminal of the cascode circuitry is coupled to the second terminal of the first transistor. The fourth terminal of the cascode circuitry is coupled to the second terminal of the second transistor. The IC also includes dynamic biasing circuitry having a first terminal and a second terminal. The first terminal of the dynamic biasing circuitry is coupled to the first terminals of the first and second transistors.
